Application filed August '5,

To all whom, it may concern:

Be it known that I, P ILIrDEais'a citizen of the United States,. residing at Mattawan, in the county of Van Buren and State of Michigan, have invente'd'certain new and useful Improvements in Grape-Pomace Heaters, of which the following is a' specification. I

-My-invent1on relates to :devices for heatingfgrape pomace preliminary to. the prepa ration of bottled grape juice. but it will beappreciated by those skilled in the art that I the employment of a heater of this kind is not necessarily limited and restricted'to his particular use. 7

In the commercial production of grape juice it is'cust'omary to heat the grape pom- I ace. before pressing .for the ent raction of the juice, for the purpose of developing the flavor and securingthe proper colon .In carryin out this heating method it is, of course, desirable' to-use some sort ofa vessel not readily corrodible, and it is essential that the ,pomace shall not be overheated, and, shall travel through the device continuously, so that the heating operation is uninterrupted. f A 7 -To accomplish these and other results I 'have invented the 'iinprovements hereinafter. described in detail in connection with a preferred embodiment of the invention illustrated. in'th'e accompanying drawings forming apartof this specification, and throughout the various views of which like reference characters refer to the same parts. Inthese drawings,Figure 1 is a central longitudinal, fragmentary. vertical section through, one of the embodiments of their-r vention; Fig. 2- is a cross section online 2-2 of Fig. l the parts being viewed in the direction indicated by the arrows, and Fig. 3 is a section throughthe shaft, illustrating the manner of attaching thestirring blades thereto. 1

- By referring to the drawings, ,it willbe. apparent that the machine or appliance is supplied with apair of end castings. l0 and 11, preferably madeofcast-iron, and-each provided with a. pair of supporting feet 12-, 12, the two "castings at their lower portions being connected together and spaced apartthe proper distance by the pair of rods or. bolts 13, 13, and the spacing pipe'se'ctions or sleeves 14 surrounding the rods or bolts Specification of Letters Patent.

which is adapted to support: a thinl'nietal sheet 16 forming the \uterwallofla hot- 1 ing and conveying blade '36, preferablyof water jacket or compartment 17 of substantially U-shaped form in cross section,- as

shown in Fig. 2. Along each of itsupper edges, the plate, 16- has fastened thereto a.

.small stiffening angle bar 18 for'the obvious purpose of strengthening the edge of. the

plate.

Each end face a bracket 19 and each supplied with abearing 21, such bearings accommodating a. revoluble shaft-22 which extends through the casing of the machine, through alin'ed holes 23 the two end members of the ma-.

chine, each of theglatter being equippedavith a stuffing box 2% surrounding the shaft ust outside of the casmg.

The appliance has an inner 'or .p'omace casting has boltedtojits outer compartment 25 composed oftwo aluminum end plates 26- and 27 disposed just inside of the end-lmembers 10 and 11 and having around theircurved peripheries, inwardly extended flanges 28 and 29 -which support and bonfine a thin, curved aluminum plate 30 forming the bottom andside walls ofthe compartment 25 and having alongkitsktop 'edgesthe stiffening'angle bars 31, 31'; The

shaft 22 has adjustably fixed thereto inthe chamber 25 a plurality of sleeves or collars 32 adapted to be held in adjusted position on the shaft by set screws 33', each collar having an outstanding projection'34 to which is fastened,- by screws 35, a stirring or agitat;

aluminum. As is clearly indicated in Figs. 1 and 2, these blades are arranged. spirally around the shaft for the'purposeof making the power necessary to. revolve the shaft more uniform, and forthe' further purpose of gradually advancing the pomace from one end of the chamber to the other. Abovesone end of the appliance I employ an admission conduit or. -pipe 37, through which the pomace is fed to the -heater, and at theother'endbetween the end castings; Each end casting has on its inner surface an inwardly exof the device I supply the endcasting- 1-1 with a discharge spout-38. In-devices' ofv this character it is preferable to heat the water of the jacket in compartment 17 'by means of steam delivered thereto, and in order to secure a 'uniformheatin g of the jacket Iuse a steam-pipe 39 perforated along its entire 'lengt-hwithin. the water chamber at;

40, supported at one end at 41 in the end member 11, and-having asuitable'conneetion with the external pipe 42 leading to any suitable'source of steam and equipped with a control valve 43. Chamber 17 has in ad'- dition a water overflow pipe 44, shown in Fig. 2, which determines the height to which the. water may rise in the jacket compartment. I

It should be clear to those skilled in the art that the pomace chamber 25', being com- .posed of aluminum, is practically non-corrodible when grapes are used, the same re-' marks applying to the blades 36, although it is' not necessary to have the shaft 22 of such material. because it is disposed above the height towhich the pomace rises'in the chamber. y 7

Assuming that the compartment 25 is heated by the hot water in the acket 1T,the-

temperature of which can never rise above 212, because the cl amber 19 open at 1ts top to the atmosphere,t1e pomace is fed .to thecompartment 25 through the pipe 37, becomes heatedand is caused to travel along the compartment by the stirring blades, fi-

nally being discharged through the spout 38, the blades not nly effecting'the travel of the pomace, but'also stirringthe same to secure a uniform temperature throughout of the body being'treated.

The appliance is readily taken. apart for cleaning, that is, for cleaning other'than can be readily accomplished without 'disnian tling, by loosening the set screws 33, WLitlr.

drawing the shaft-22 longitudinally through the bearings and stu'flin'g boxes, whichwill permit the withdrawal of the aluminum ends I 26 and 27' and the 'sheet'of metal 38, as well as the aluminum blades 36. These can then be scoured and cleaned as much as is necessary, and can be readily replaced.

Owing to the fact that the stirring blades 36 are normally adjustable around their supporting shaft 22, the speed of travel of the pomace through the heater 'can be readily varied, eitherby changing the positions of these blades or-by varying the speed of rota tion of the shaft.

I do'not Wish to be limited tothe exact features of construction herein shown and described, because the invention is suscepti ble of different embodiments and the ele ments entering'into the appliance herein set forth may be modified structurally within comparatively wide limits'1without departure from the heart and substance of the in vention. l
